Detection of Weapons in 2D Image
Demčák, Ján ; Spurný, Martin (referee) ; Drahanský, Martin (advisor)
This bachelor thesis deals with detection of weapons in 2D image. In the theoretical part of the thesis the term weapon was defined and the possibilities of detection of weapons in image with using classic methods and deep neural networks were mentioned there. The key steps of image processing, objects classification and detection were described. The overview of frameworks, libraries was presented. To implement the pratical part of the thesis, 3 models were chosen. The first classic model with using HOG transformation. The second CNN model with priority target detection accuracy and with two different neural network architectures as classifiers. The third model with YOLO network architecture had as priority target real-time detection. The essential part of each model was choice, or more precisely creating suitable dataset. What followed was the construction and implementation of models and the evaluation of obtained data.

Obermayer, Jan ; Fiala, Miloš (advisor) ; Brych, Jan (referee)
Title: Basic Firearms Training for The Police of the Czech Republic Objectives: The objective of the thesis is to elaborate on basic firearms and shooting technique training within the scope of the basic training course of the Police of the Czech Republic. Methods: The fundamental methods used in the thesis are the data collection method, applied not only for studying literature, but also in the subsequent selection of professional experience and knowledge. Another method is the analysis method, used for expert evaluation, verification, the quantitative, material, as well as interpretative and comparative analysis. Another basic scientific method is applied, for the purpose of describing basic methodological and tactical procedures and also creating a set of preparatory training sessions. The method is referred to as information synthesis. Results: The output of the thesis is creating a complex view of the issue concerning firearms training for the Police of the Czech Republic according to today's methodology, tasks and objectives laid on this education course. Despite the curriculum of the firearms training being the same for several years, there is a definite improvement and effort to draw the training closer to actual situations and operations. I find that developing methodological guides and...

Production process for a replica of a historic firearm
Čech, Jakub ; Chladil, Josef (referee) ; Kalivoda, Milan (advisor)
This thesis deals with the production of a prototype pistol with a wheel mechanism. In the theoretical part the history is described together with the terminology focused on firearms up to the 17th century. This is followed by a demonstration of the design of the gun in the software version and a demonstration of the machines that were used for the production of the prototype. The practical part describes the production process of some components needed to make the pistol mechanism, together with the overall evaluation of the final product.

Electromagnetic recoil system for simulated weapons
Vladík, Jakub ; Jirgl, Miroslav (referee) ; Baštán, Ondřej (advisor)
Main goal of this work is to analyze the feasibility of an electromagnetic recoil simulator on weapon replicas. The thesis explains the basic function of self-loading firearms based on the HK 416 weapon and then the concept of recoil and its meaning. Lists today's recoil compensation options. It then defines possible electromagnetic solutions as a replacement for the existing pneumatic recoil system. Some posibble solutions mentions DC motor, solenoid, linear motor and railgun as possible. The thesis lists DC motor, solenoid, linear motor and railgun as possible solutions. The best solution is a tubular linear motor combined with a power supply containing Li-pol batteries.

Attention will be paid to the definition of forensic ballistics, placing forensic ballistics into the system of criminalistics and areas of forensic ballistics. Particular objects of forensic ballistic examination, especially specific tangible and intangible assets examined by forensic ballistics, will be presented. According to objects of forensic ballistic examination will also be presented the issue of ballistic traces. Particular sections of forensic ballistic examination will be defined at the end of the first part. The second part is focused on procedural aspects of forensic ballistics, especially its connection with other forensic sciences and methods of criminalistics and criminal procedural law. The main idea of this part is to connect forensic ballistics as a forensic science with forensic expertise...

Krajíc, Petr ; Kafková, Helena (advisor) ; Filip, Michal (referee)
TITLE: Technique: cutting weapons in the nineteenth and twentieth centuries - art and war AUTHOR: Petr Krajíc DEPARTMENT: Institute for professional development, faculty of education SUPERVISOR: Mgr. Helena Kafková ABSTRACT The target of the thesis is to present cold weapons not just as means of hunt, everyday use, but also as an attribute of the worrior art and to present reasons and changes, that lead to continual retirement of cold weapons to marginal possition.

I present, in six chapters, basic patterns of use and kinds of cold weapons, described chronologically in concord with their history. I also study the period of the First Czechoslovak Republic. The major contribution of the thesis is acquiring basic knowledge from history, technical development and also the reasons of various changes and presentation of the weapon as artifact of its individual value.

The main method for the production of this thesis was to study literature and other texts, or materials related to the given topic. The thesis is divided into several chapters by type of weapon (cold, firearms) and by continents, where the weapons occurred. Then I focused my research on the phenomenon of arms in the film industry, and the question of arms and related violence and also the issue of preventing violence, bullying and crime. Keywords: Art-work, ornamentation, gun, cool gun, violence, aggression, prevention
